REVERSIBLE WINDOW.

SPECIFICATION forming part of Letters Patent No. 487,1 18, dated November 29, 1892.

Application filed December 16, 1891. Serial No. 415,207. (No model.)

I or for other purposes.

The invention also consists of certain parts and details and combinations of the same, as willbe hereinafter described,and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front View of the improvement with the window-sashes closed. Fig. 2 is a transverse section of the same with the sashes in an inclined position. Fig. 3 is an enlarged transverse section of the sliding stile and hinge. Fig. 4 is afront View of the same with the sash-stile attached. Fig. 5 is a sectional plan view of the same on the line 5 5 of Fig. 4. Fig. 6 is a similar View of the same with the sash reversed. Fig. 7 is a side elevation of a hinge of modified form. Fig. 8 is a front view of the same. Fig. 9 is aside elevation of the same in an open position. Fig. 10 is an enlarged cross-section of the catch on the line 10 10 of Fig. 2. Fig. 11 is a perspective view of the improvement as applied and showing one of the sashes open; and Fig. 12 is a sectional plan View of part of the improvement, showing the sash-stile and sliding stile engaged when the window is in a reversed position.

The improved reversible window A is provided with the two stiles B and B, connected at their middle, on the outside, by hinges O and 0, respectively, with the sliding stiles D and D, respectively, and directly with the frame E of the window. As shown in Figs. 3, 4, 5, and 6, each hinge (J or C is composed of two members, of which one member is attached with its leg 0 to the stile B near its front and on one side thereof near the middle,

as plainly shown, the said leg 0 being provided with a forked head 0 engaged by a tongue 0 projecting forwardly from the upper end of the leg 0 of the other member. The leg 0 is secured to the sliding stile D or to the window-frame in line with the leg 0 when the windowAis closed. The tongue 0 is connected with the forked head 0 by a pivot-pin C, so that the window A can swing with its upper part inward and downward, turning on the two pivots of the two hinges O and C, located directly opposite each other, as plainly shown in Fig. 1. The leg 0 of the hinge O or O is attached to abead F, extending upwardly on the side of the stile B from the head 0 as plainly shown in Fig. 4, the said bead being formed in its front with a semicircular groove or recess F, adapted to engage a semicircular offset G on the bead G, attached to or forming part of the sliding stile D, the said head G extending downward from the head of the leg 0 at the front of the said stile D, as will be readily understood by reference to Figs. 11 and 12.

When the windowAis in a closed position, the rear edge of the bead F abuts against a shoulder H, formed on the stile D, the said shoulder extending upward from the hinge G, as plainly illustrated in the drawings. In a like manner the rear edge of the bead G forms an abutment for a shoulder I, formed on the side of the stile B at the rear and extending downwardly from the hinge. Now when the window A is closed, as illustrated in Figs. 1, 3, 4, and 5,1:he rear end of the bead F abuts on the shoulder H in the upper half of the window, while on the rear edge of the bead G abuts the shoulder I in the lower half of the window. A tight unbroken joint is thus formed between the stiles B and. D, so that water or moisture is not liable to pass from the outside of the window to the inside.

In order to establish a circulation of air in the joint of the two stiles at the rear, each of the stiles is provided with a vertically-extending semicircular groove J or J, located directly opposite each other, so as to form a circular opening when the window is closed, as illustrated in Fig. 5. As plainly shown in Fig 5, the hinge O or C does not project beyond the front face of the stiles B D or B D, as the center of the pivot of the hinge is in line with the vertical axis of the round offset G of the bead G. Thus when the window A is reversed by turning it on the hinges O and O, the groove F in the bead F fits onto the projection G of the bead G and the window stands in a vertical position again, but with the outside of the pane of glass at the inside of the room.

In order to make a very tight joint between the two stiles B D and B D, catches K are preferably arranged near the ends of the stiles, as plainly shown in Figs. 2 and 10. Each set of catches K is formed of two members K and K of which one is attached to the stile B or B and the other to the sliding stile D or D, respectively. The member K is provided with a wedge-shaped projection or point K engaging an incline K formed on the inside of the other member K so that when the window A is turned into a closed position the wedge K enters the incline K, and thus draws the two stiles closely together. It will be seen that a reversible window constructed in this manner can be readily moved up and down by the stiles D and D, traveling in the usual grooves in the window-casing, and the window can be reversed in the manner described for cleaning the outside of the panes, inserting new panes of glass, or painting outside of the frame, as the case may be. It will further be seen that the stiles D and D remain in the grooves in the casing at the time the window is reversed. The two windows A in one casing, as shown in Figsl and 2, may be conveniently and independently reversed whenever desired. As shown in Figs. 7, 8, and 9, the pivoted heads 0 of the two hinge members are connected with each other by a link C and the heads are also formed with two abutting shoulders C to prevent the members from opening rearwardly.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a reversible window, the combination, with a window-frame formed on the side of its stiles with beads extending upwardly from the middle, of hinges located opposite each other and connected by one member to the said beads at the middle of the stiles, sliding stiles connected with the other members of the said hinges and each formed with a shoulder for engagement with the rear edge of the said window-stilebead and with a bead adapted to be engaged by the front edge of the said window-stile bead, substantially as shown and described.

2. In a reversible window, the combination, with a window-frame formed on the side of its stiles with beads extending upwardlyfrom.
